UNITED STATES DISPENSER I 'Harold F. Johnston and Emerson H. Tompkins,

Waterbury, Conn., assignors to' scovill Manu- Y t v facturing- Company,Waterbury, Conn., a corpoi-ation of Connecticut Application June 15,1936, Serial No. 8 5,286 2 Claims. (01. 215-78). 7

This invention relates to improvements in dispensers such as are used asstoppers for containers and relates more particularly to that type ofdispenser adapted to be positioned in the neck of a bottle and employinga depressible plunger that normally projects slightly above the closurecap and whereby limited quantities of liquid can be released as into thepalm of a hand by slightly pressing in on the plunger.

The invention further relates to dispensing means such as are adapted tobe used for the closure of receptacles such for instance as bottles andemployed for containing face and hand 10- tions or other toiletpreparations, condiments,

or the like. Our dispenser 'is of the gravity type, which is providedwith a discharge opening that is normally closed but which may bemanually opened when the container is inverted and its conical plungerpressed in more or less according to the quantity of liquid desired.

An object of the invention is to provide a simple and practical form ofdispenser which may be manufactured largely from sheet metal, quicklyassembled and conveniently attached, as

by threads, to the mouth of a bottle; further to provide a dispenserwhich will permit the liquid to freely flow therethrough when thecontainer is turned bottom up to dispense the liquid when pressedagainst an object such as a persons hand.

A further object of the invention is to include a depending tubularcasing havingan annular external flange around its upper end portion,that is secured as between the cap and a pack- 5 ing covering the mouthend of the bottle and which casing is provided with a perforated bottomadapted to support a spring that actuates the plunger.

Another important feature of the invention is to provide a constructionwhich may be readily assembled so that the parts may be held togethertemporarily for shipping purposes by means of one of its elements suchfor instance as a sealing washer and which is adapted to be permanentlyheld in an operatable assembled position coincident with the assembly ofthe cap upon the mouth of a bottle or container.

Our invention further consists in the constructions and in theinterrelations and combination of parts hereinafter described and moreparticularly pointed out in the claims and as will be more readilyunderstood by referring to the accompanying drawing forming a part ofthis specification, and in which 7 Fig. 1 shows, on a slightly enlargedscale, a

central vertical section through our improved type of dispenser shownattached to the mouth portion of a bottle and wherein the metal plungeris provided with peripheral guides.

Fig. 2 is a detached bottom plan view of the 5 dispenser shown in Fig.1.

Figs. 3 and 4 show a top plan view, and cross section respectively takenon line 1-1 of Fig. 3, illustrating a shell form of plunger as shown inFig. 1. 10

In the drawing I0 represents a bottle neck provided with a thread II toreceive the rolled threads i2 in the depending annular flange portion I3 of a closure cap M. This closure cap is formed of sheet metal of asize to snugly fit 15 and close the bottle and inclose the otherelements of the dispenser including the conical plunger I5 whichnormally extends out through a central opening I6 in the top oftheraised portion ll of the cap I3. This plunger is nor- 20 mally retainedin its raised position by means of a spiral spring "la the upper endportion of which is seated against the underside of the plunger and thelower end of which restson the. lower internal annular ledge portion I9of the 25 cylindrical support 20 that is disposed into the neck of thebottle. The upper end of this support is provided with an outwardlydisposed annularfiange 2| that is engaged by the inner face of theannular shouldered portion 22 of the 30 cap' and secured as between itand the packing washer 23 that covers the end of the bottle and extendsin against the outer Wall of the cylindrical portion of the supportbetter to support and center the same. 35

In the drawing, as will be seen, the plunger is provided on its loweredge portion with spaced apart guide members 25a, against which theupper end of the spring la is positioned. The depending end portions ofthese guide members 40 25a are disposed in the cylindrical support in away to slidably engage the inner wall thereof to permit the lowerportion of the plunger to be pressed down into the casing against theaction of the spring and thus produce an an- 4 nular opening in the capsurrounding the tapered plunger in a way toallow the liquid to pass out,through the dispenser. In this dispensing operation the liquid passesfrom the bottle into the lower end of the casing, past the lower edgeportions of the plunger into the chamber 26 of the closure cap and outthrough the opening, that is of course when the bottle is turned bottomup and the plunger is pressed inward. Due to the 55 .s an

use of a conical plunger in a given size of round hole it will beapparent that the size of the outlet produced by the pressing in of theplunger will depend upon the amount of pressure applied when operatingthe plunger.

Having thus described our invention what we claim and desire to secureby Letters Patent is:

1. A liquid dispenser of the class described including a closure capadapted for attachment to the open end of a container and having adischarge opening therein, a support member extending within the openend of said container and having means to permit the passage of thecontainer contents therethrough, means for holding said support memberin cooperable assembled position relative to said cap coincident withthe assembly of the latter to its respective container and a plunger forclosing the opening in said cap having integrally formed spaced guidefingers slidably engaged in said support member, and a spring engagedbetween the support means and the latter to its respective container, ahollow conical shaped plunger, said plunger provided at its base endwith integral outwardly formed spaced fingers having slidable guidingconnection with said support, and a coiled spring compressed betweensaid fingers and said support for norsaid opening.
